Crap
I use a T470 at work. I hate it.
Moderate weight, no biggie. Reasonably powerful. Nice form factor.
However, it absolutely blows chunks when being docked and undocked. I repeatedly have to fiddle with network devices to get it to work. The other day it was the worst yet. I had to remove my network device in device manager to get it to enable. Not to get it to pick up the network as if it was diconnected. To get it to work at all. Why was it disabled when undocked? PITA.
Waking from sleep is slow. This may be a byproduct of having to communicate with the docking station. I don't really care.
Keyboard is nice though.
I'm far happier with my HP Envy. It's a previous generation I7 and is faster and more reliable than the 470. Cost less too.
